During the planning phase of a multi-storey wood-frame building, the project scheduler identifies that craning activities for floor joists and roof trusses are on the critical path. The crane is also scheduled for another project concurrently. What is the most effective strategy to mitigate the risk of schedule delays due to crane availability?

Question: During the planning phase of a multi-storey wood-frame building, the project scheduler identifies that craning activities for floor joists and roof trusses are on the critical path. The crane is also scheduled for another project concurrently. What is the most effective strategy to mitigate the risk of schedule delays due to crane availability?

Answer options:

• Increase the budget for material waste.
• Pad the schedule by adding 20% extra time to all subsequent tasks. ✅ Identify alternative hoisting methods or negotiate exclusive crane use for specific, critical windows of time.
• Reduce the quality control inspections to save time.

Correct answer: Identify alternative hoisting methods or negotiate exclusive crane use for specific, critical windows of time.

Explanation: To mitigate schedule delays due to crane availability on the critical path, identifying alternative hoisting methods or securing exclusive crane use during critical periods directly addresses the bottleneck. Padding the schedule or increasing material waste budget does not resolve the core issue, and reducing quality control is not a viable or safe option.
